Special Operations place great physical demands on personnel. In most Navy settings, greater physical demands are associated with greater musculoskeletal injury rates. Within the Special Operations community, Special Boat operators have a unique set of risks. Small boats operating in the open ocean are subject to large shock and vibration forces. Exposure to such forces can lead to discomfort, injury and performance degradation. In an effort to begin assessing the prevalence of injuries related to operations in small Special Operations craft, a self-report survey of injuries (SBUIS) was administered to 154 operator personnel drawn from Special Boat Units 12,20 and 22. Sample mean age was 32.0 ± 5.9 yr., mean years of military service was 12.0 ± 5.5, and mean time in Special Boats was 4.7 ± 3.0 yr. The SBUIS obtained demographic information, unit assignment and role information, past general pain levels, details about up to three specific injuries, and exercise history information. Specific injury information included type and location of injury, and type and duration of care for that injury. Of the respondents, 95 reported one injury event, 11 reported 2, and 5 reported 3. The 121 injury events resulted in 153 separate injuries.The most prevalent type of injury was sprains and strains (49.3%) followed by disc problems (7.9%) and trauma (7.9%). The most prevalent injury sites were the lower back (33.6%), knee rates for the Navy as a whole. Hospitalization incidence for the survey respondents was 2,687 per 100,000 person-years exposure. The overall Navy rate for the combination of injuries reported in this sample was 479 per 100,000 personyears. Only constructionmen (CN), seamen (SN), firemen (FN), and airmen (AN) had greater hospitalization rates than SBU respondents. We conclude that SBU personnel are at greater than average risk of injury associated with SBU training and operations. These findings need to be confirmed. If confirmed, methods to reduce the injury risk must be identified and implemented.
